Charlie,
There are existing global databases of surface water boundaries, water
quality, DEMs, etc. In some cases more than one. Those could be one
starting point - license permitting. The other would of course be OSM
itself, which already contains surface water features. Adding a
Maybe, information related to temperature, discharge etc. Could be handled
by SOS... so maybe you're looking for an open SOS linked with a open WFS of
rivers?

Hi Charlie,
I like your idea, but there are many issues to discuss.
1. What is the goal?
Depending on users interest (hydrologists, biologists, ..), average
stream can be represented as line or polygon.
Set of attributes depends on user needs. Even simple water level changes
in time. Without
The USGS has a KML map of their stream gauges and water quality sensors in
the US. Here's a good starting point: http://water.usgs.gov/wateralert/
Getting an embeddable realtime view can be more difficult - I have a
regional example here
Dear Charlie,
The idea is interesting, but I concur with Robert that -in order to provide
some more educated feedback, it would be also interesting to know a little
more about your initial driver.
I have worked in the past in surface hydrology and water resources
management, and more recently I
